  • SEPARATOR SUITABLE FOR USE IN LITHIUM ION BATTERIES
    Publication number: 20240413485
    Abstract: The invention pertains to a separator suitable for use in lithium ion batteries which comprises a core paper comprising 30-70 wt. % aramid shortcut fiber, 10-45 wt. % PET, and 5-40 wt. % of a binder, the core paper having a grammage of 5-30 g/m2 and a thickness of 5-30 micron, wherein at least one side of the core paper is provided with a coating layer, said coating layer comprising refractory particles and a coating binder, wherein the separator has a surface pore size on the side of the paper provided with the coating layer which is such that at least 90 number % of the surface pores has a pore size of at most 0.5 micron.

  • Aramid-based paper with improved properties
    Patent number: 11686048
    Abstract: An aramid-based paper comprising at least 90 wt. % of aramid material, the aramid material including at least one of aramid shortcut and aramid fibrid, the paper including at most 40 wt. % aramid pulp, calculated on the total amount of aramid material, wherein the paper includes 0.1-10 wt. % of polyamido-amine epichlorohydrin (PAE). It has been found that the incorporation of 0.1-10 wt. % of polyamido-amine epichlorohydrin (PAE) into an aramid-based paper including at least 90 wt. % of aramid material calculated on the weight of the paper not including the PAE, the aramid material including at least one of aramid shortcut and aramid fibrid, the paper including at most 40 wt. % aramid pulp, leads to a surprising improvement of the z-strength and the tear strength of the paper.
